Fabrication Techniques for Organic Electrolyte Battery 
A report describing the fabrication and testing of 
silver chloride electrodes for use in organic electrolyte 
batteries discusses the experimental procedures used, the 
test results and the development of parameter ranges 
used for fabricating electrodes. The experiments were 
part of a research effort to develop a battery capable of 
producing fifty watt-hours of energy per pound of 
battery weight and operable over a temperature range of 
540 Ctol2l°C. 
Electrodes were fabricated from silver chloride by 
pelletizing, sintering, hot press binding and paste binding 
silver chloride on expanded metal grids of nickel or 
silver. Each technique was investigated by a statistically 
designed factorial experiment. The factors considered 
were parameters associated with the composition and 
preparation of the electrode and included pressure, 
temperature, binder type and filler type. 
The electrodes were tested in a test cell which used 
a silver-silver chloride reference electrode. Both half cell 
and full cell tests were conducted. Electrolytes of 
phenyltrimethylammonium hexafluorophosphate or 
morpholinium hexafluorophosphate were used. The tests 
conducted included a galvanostatic transient test to 
determine electrode resistance and concentration po-
larization, transfer function measurement to determine 
electroactive surface areas and a cell discharge test. 
The result of the research shows that the internal 
resistance of the test cell is low and caused by diffusion 
limitations. Good coulombic efficiencies (75%) can be 
obtained at room temperatures and the cell continues to 
operate at low temperatures. The report contains val-
uable information on pelletized electrodes and a basis is 
established for future experiments because parameter 
ranges which can be used to construct mechanically 
sound electrodes are presented.
